The speaking machine

An original fiction passage set in the nineteenth century.

Before the committee entered, Clara listened to the machine breathe. Each pull of the hidden lever filled its leather bellows; each release sent air through the narrow reeds concealed behind its wooden mouth. To anybody else, the sounds might have been a collection of sighs and clicks. Clara had heard them every evening for six months. This morning, the left bellows returned a fraction too slowly.

Her brother Elias stood beside his invention, polishing a brass screw that was already bright. He had slept little. When Clara mentioned the delay, he answered that the crowded hall had made her anxious. Yet, as the committee took their seats, she saw him test the lever twice before drawing the curtain aside.

Elias explained that the machine had been prepared to answer a simple question. He faced its painted features and asked, 'Do you understand me?'

The lever descended. There was a click, followed by silence.

Several committee members bent over their papers. Clara did not look at them. A small retaining pin beside the machine's jaw stood slightly above its socket. She caught Elias's eye and touched one finger to her own chin. He followed her signal, pressed the pin into place and announced that he would repeat the trial.

This time, a thin vibration gathered inside the wooden head. It sharpened briefly, almost taking the edge of a word, before collapsing into a rush of air. Clara heard the beginning of 'yes' because she knew precisely where the sound was meant to travel. Around her, chairs creaked. A reporter near the aisle covered a laugh with a cough.

'It spoke,' Clara said.

She had intended the words for Elias, but the sudden quiet carried them across the hall. One committee member asked whether she had heard the complete answer. Clara looked at the wooden mouth. In all their private trials, she had supplied the lever while Elias adjusted the reeds; she knew every failure that had preceded this one. What she had heard was closer to speech than any of them.

'Clearly enough,' she replied.

Elias lowered the curtain soon afterwards. When the hall had emptied, he removed the retaining pin and held it towards the window. A shallow bend ran through its centre.

'You were right about this,' he said. 'Another attempt might have split the valve.'

Clara waited for him to say more. At last, she repeated that the machine had spoken.

Elias placed the pin on the table. 'You knew the answer before it began.' His voice contained neither anger nor gratitude. 'The committee did not.'

Clara remembered the vibration straining towards the familiar syllable and the reporter's hidden laugh. She could not decide which had influenced her more: six months of attentive listening or six months of wanting Elias to succeed. As they reached the door, the machine released the last air from its bellows. The faint sound seemed to follow them, still unfinished.

"The passage convincingly presents Clara's loyalty as both a source of insight and a cause of self-deception."
